QTR-Quadtone RIP

Paul-

I just reprinted the, following your suggestion.  The "overspray" was
significantly reduced, but is still present.  The type, itself, was
also a bit better defined.  However, the QTR print of the full 1080dpi
file is still unquestionably superior.  What is it that QTR does
differently (and apparently, better)?

Perhaps what this does show, at the very least, is that when printing
a large file to an Epson printer, downsample to 720 dpi (or 360dpi, as
appropriate)in Photoshop, or other program, before sending it to the
printer.
